-and use ,my invention, I will `proceed to .1de-

rscribe `its eonstructionrand operation.

V.In the drawings,.A-represents a gear-wheel, to which isattached apinion, B,both of which take bearing-on a stud, U, in kthe arm D,or upon any other suitable support. E vrepresents `the head of the binding-arm, or arm for ,carrying the binding `material around :the bundle. Attached to the A.end of `the stud-O `is apart, FF/to whichis pivotedthe handle Gmofthe jawsd f rthat `hold the .cut or free end ofthe wire. One of the jaws,.asd,.may be apartof the body or handle G, while the othenf, ispivoted 'to it, as shown, or both jawsmaydike .the jawvf) .he pivoted to it. The .pivoted `jaw j has` aprojecting l portion `or lug, o, that strikes against the legF asthe jawsarelraised, Vso .opening them, as shown in AFig. Ifbothjawsare pivoted, then both .may be provided with the projection n. The inner Afacespf ythe jaws df are cnt longitudinally, lwith V-,shaped grooves that, .ihycrimpingthe wire, enablethe jaws more easily to hold it. "These faces may, however, bemade plailn Onelof the jaws may be yprovidedwitha tooth, 1", Fig. 8, to aid in 4holding the wire.

The part F is divided, as sho\vn,.into two legs, F lF', thatstride .thewire-liolcler G, and opener close the jawsd f, as the `latter care, respectively,.driven .up or -down bythe-.camrim `N andcam-latch a a'. The cam-latch a. a. is pivoted at p `on the support M, that,.to gether with the caln-rim'N, isattached to and shouldy form apart =of .theAgear-wheel A. K

represents any revolving twisting device, `as av slotted pinion, .that `takes fbearin g .on any suitablesupport, asthe parts H .I Lattached `to the arm D. The/.cam block Lor latch a a tical, or nearly vertical, cutting-edge, as shown in Fig. 21.

The modification shown in Figs. 13, 14, and 15, is for the purpose of giving the wire-holder d f a reciprocating movement longitudinally or endwise. This movement is effected by making the can] Nslightly irregular, as shown, (instead of its being described in the arc of a circle) and by adding tothe gear-wheel A a second cam, P, Figs. 13, 14, 15, 16,17, and 18, that is used to drive the wire-holder in onc direction, as from the twisting device, as the gear-wheel revolves in one direction to twist the wire, while the raised portion or ledge M ofthe cam N drives it back as the gear-wheel revolves back after the twisting is done.

With this modification the pivot-orifice t is elongated, as shown in Figs. .16, 17, 18, and 23 to allow of the end movementof the wireholder. Instead of the pivot-pin a cap, b', Figs. 19 and 20, over thefarin yG of the wire holder, retaining the latter` in the part F F', may be used. 2

The cam P, working against the lug or pin c','Figs. 16, 17, 18, and 23, drives the wireholder G dffrom the twisting device, while the raised portion M of the cam N, working against the end of the arm G, drives it back. By the use of a second lug or pin, d', Fig. 23, outside ot' the cam N, in connection with the lug or pin e' in the y inside thereof, the cam P and raised portion m maybe dispensed with, as shown in'Figs. 22 and 23.l

When ready to operate, place the cut or free end of the wire in the jaws d f, or having kinked the end so as to prevent it from heilig drawn through the slot of the twisting-pinion K, place it iu the latter, when the arm E opening to receive the bundle, and then closing again, loopsthe wire around it, as shown in Fig. 1, and lays it (the wire) again in the twistingpinion, and within the inclined lips of the jaws df, Figs. 1 and 7.

At this stage of the operation, the parts being in the position sh'own in Figs. 3, 7, and 11-that is, with the arm G on the cam N, andthe jaws closed-the gear-wheel is made to revolve (either by a reciprocating rack working in the pinion B, or in any other desired manner) in the direction shown'by the arrow in Figs. 3 and 13. The location of the cam-latch a a' iwsjsuch that as soon as the twistinghas fairly commenced, the end of the arm G, passing' over the depending end a' of the cam-latch, is compelled to follow in the groove c between the latch and the cam N, so driving up the end of the arm G, and the vwireholder swinging on its pivot driving down the jaws df to the position shownin Fig. 10, when the part f', Figs. 7 and 8, of the pivoted jaw f, striking against the leg F', causes the jaws to open, so as to adlnit the wire p, as shown in Fig. 8. The wheel A, continuing to revolve in the same direction, soon carries the end of the arm G out ofthe camgroove c, so swinging the wire-holder on its pivot, and driving up the jaws d f between the legs F F', by which they are closed, and the wire seized. rlhe knife M' is so adjusted that immediately after the wire is seized by the jaws it drives its cutting-edge over the shearing-face of the twisting device, as shown in Figs. 1, 2, and 12, thereby serving the bundle, and allowing it to be thrown out or discharged from the machine, when the gear-wheel A revolves back, to its iirst position, (shown in Fig. 3,) the arm E again opens, and the operation is repeated, as before. yAs the wheel A revolves back, the arm G, owing to the end a of the cam-latch pressing' against the cam N, as shown in Figs. 1 and 4, cannot enter the groove c, but passes over the cam, thereby not operating the wire-holder.

The operation of the wire-holder when the cam P, Figs. 13, 14, 15, 16, 17, and 18, ledge M,/and lug c', or when simply the lugs d' and e', Fig. `23, are used, is evident from the previous description and theA drawings, as the form of the cams P and N is such that, after thejaws are opened by the arm G entering the groove c, the wire-holder is taken back or away from the twisting device, as shown in Figs. 14,15, 17,18; and, after the jaws are closed and the bundle discharged, and while the wheel A isrunning back, the wire-holder is drawn forward toits first position. (Shown in Fig. 13.)

It will be observed that the method of securing and operating the knife M' removes the liability of its getting loose, and enables it more easily to be sharpened without removal than when pivoted, as heretofore, to the twisting-device.

It will also be observed that the jaws d f may be used to hold cord as well as wire.

What I claim is- The combination of a rotating tying or twisting device, circular moving cutting mechanism, and reciprocating wire or cord holder, substantially as described.
